The Waratahs were dealt a blow ahead of Friday's clash with the Rebels in Melbourne when Wycliff Palu was forced to withdraw through injury.
The defending champions coach Michael Cheika named an unchanged starting line-up, despite their opening round loss to the Western Force, but according to AAP, Palu will miss their clash against the Rebels due to a knee injury.
Veteran loose forward Stephen Hoiles – who started last year's Super Rugby Final against the Crusaders on the blindside flank – replaces Palu in the run-on side.
The Sydneysiders' replacements bench for Friday's match has yet to be finalised.
Waratahs (revised): 15 Israel Folau, 14 Taqele Naiyaravaro, 13 Adam Ashley-Cooper, 12 Kurtley Beale, 11 Rob Horne, 10 Bernard Foley, 9 Nick Phipps, 8 Stephen Hoiles, 7 Michael Hooper, 6 Jaques Potgieter, 5 Will Skelton, 4 David Dennis (c), 3 Sekope Kepu, 2 Tatafu Polota-Nau, 1 Benn Robinson.
